Abstract: 20,009. Boult, A. J., [United Shoe Machinery Co.]. Oct. 3. Uppers.-Relates chiefly to improvements on the pounding-up and blocking or jiggering machine described in Specification No. 18,883, A.D. 1904, and consists broadly in the use in combination of a device for beating, pressing, rubbing, pounding-up, or jiggering the upper, and a separate device for heating the upper, the heated device being preferably arranged to engage the shoe in a line parallel with the line of the feed. The means for actuating the oscillating lever 100 is the same as in the machine above referred to, with the exception that the outer member of the cone clutch is formed upon the driving-pulley, and is considerably enlarged, while the inner member is secured to the main shaft. In addition, the rubber buffers of the previous machine are replaced by spring-pressed plungers 99, Fig. 2. In order that the blocking- tool may be rendered inoperative when desired, a spring-controlled locking-pin 151, Fig. 4, is provided. This pin is recessed at the point where it crosses the stem 148 of the tool, and normally allows the latter to reciprocate freely, but after the tool has moved backwards, it can be locked by turning the pin so that a non-recessed part engages a shoulder 159 on the stem 148. An arm 161 engages a notch in a flange 163 on the lever 100, and holds the parts in this locked position. In another form of locking-device, the stem is fitted with two flanged toothed sleeves, which are adapted to engage one another when the stem 148 is in its rearmost position. The combined smoothing-devices and rests 171, which replace the rests 170 in the old machine, are provided with reverselycurved faces 175, 173, Fig. 7, to engage the side and shank of the shoe respectively ; they are connected by pins 181 working in curved slots to brackets 177 forming part of the machine frame. Each device is normally pressed forwards by a spring plunger 179, and is provided with upward extensions 187 of considerable weight, so that they will vibrate with the frame of the machine and effect a hammering action upon the edge or corner of the shoe. The portions 175 of the devices overhang the bottom of the shoe at this point. If desired, only one smoothing-device may be used ; this is positioned to act on the upper immediately after the blocking &c. tools. Means are also provided for heating the upper. These means consist preferably in heating one or both of the smoothing- devices, though other independent means may be employed. The heating may be effected by gas, alcohol, steam, or other means. Fig. 11 shows the arrangement when steam is employed. A steambox 191, having inlet and outlet pipes 193, is arranged adjacent to the smoothing-devices 171, and on its front side is arranged a verticallymovable plate 195, which is held in yielding engagement with the devices 171 by a spring 197. The pounding-up and blocking tools are also heated by reason of their positions adjacent to the heated smoothing-devices. The heated smoothing- devices may be used alone for smoothing and finishing the sides of the shoe, the blocking &c. tool being rendered inoperative as above described. Specification No. 20,009A, A.D. 1905, is referred to.
